my tap handle is a lift to startwater push to stop left for cold right for hot i just set it by hand of thermometer push it down to stop the water and the attach the hose and turn it on its allready set at the desired tamp i want then
Yes, I have the same "perfect python" situation like that too, its a bathroom faucet (very modern single spout thing) which had temp adjustment completely separate from on/off/force because temp is sideways rotation, whereas on/off/force is up/down... its absolutely perfect for single-person distant tank refill situations. I've often recommended this to others, thinking of it as a choice thing when one is remodeling one of the house sinks... but I recently had a discussion with a person at a shop of plumbing fixtures and she said those types of models are still quite rare on typical faucets and there have actually seemed to be fewer models like this in recent years. Makes one wonder whether there might be some sort of less hit or miss solution out there in the professional restuarant world or something.
The other question is still something I find unsatisfying (vaguely) whenever it gets discussed here on TFF. I agree with jmkgreen that its not a question of us simply not needing it discussed because we can use cold. I feel that yes, we can all use just cold water in some situations when the overall tank volume and amount changed are small enough but that there are just times when people will either need to change larger percentages or when they are cycling and would rather do everything to keep the growth speed encouragement up as high as possible and so would like to "temperature match," making it a reasonable question about whether some pipes/boilers present a problem.
On TFF the question gets the added complication of us having mostly UK but also significant USA participation, not to mention all our valuable others out and about the world! I find myself sort of dissatisfied with both the USA "answer" that we have almost exclusively "fiberglass-lined" hot water heaters (tank style) and so have nothing to worry about and of course for me as a USA member, the answers for the UK side (who have attic tubs with dead birds and wooshy boilers and other unfathomable artifacts sounding like a movie set
) often digress into pure entertainment, lol.
On the USA side its true we mostly have these "glass-lined" electric or gas heated tanks and we mostly all agree there's not a worry of too much copper or other problem-causing metals... but one still hears occasionally that hot water sitting in copper pipes, even outside the hot water heater itself, will potentially acquire too much metal. In the USA one sometimes hears warnings to "run the water that's sat overnight out of your pipes" before filling the morning coffee-water kettle. I just wonder if anyone feels there's still a case for maybe doing copper measurements of if usable cheap/accurate testing is available/desired?
And on the UK side of this I've had a few UK members do some pretty nice explanations of the different household water systems in evidence historically thoughout the the islands over there, but there still seems to be room for someone to do a wonderful summary that explains the major divisions one could simplify it down to. To me it seems obvious there must be some of the old funny systems where there are open attic tubs for gravity feed (some say these are -always- heating system only and never part of the ground-pressure-fed drinking water pipes) but also systems with non-copper hot water tanks and also probably a lot of "instant" hot systems, which are more in evidence in Europe in general than in the states.
Any takers?
